another bug i've noticed is going to this panel and strafe on it then get stuck and afterwards use the unstuck and with being stuck on the panel it's pushing you up so when ur unstuck you jump high and that's how many players can go up there and its unfair for zombies + you can go up there by other ways without abusing any bugs and here's a demo : https://file.io/0IV88ENSDx3O
not sure too how this bug could be fixed but i think it should be reported.
